Small 4.2 Volt Rechargeable Battery Special Design Environmental Protection
Model: 14.4V 2200mAh
Specification: 38mmX38mmx72mm
Features: effective discharge rate ≥75% under working environment of -40°C, cylindrical 18650 low temperature lithium battery, charge cutoff voltage of 16.8V, discharge cutoff voltage of 10V, working current of 1.1A, maximum working current of 2.2A
Applications: Measuring instruments, meteorological instruments, polar surveys
Compared with Seal lead acid battery, lifepo4 battery has many advantages:
1. Green: Non-Toxic, comfort to RoHS.
2. Long cycle life: > 2000 cycles, while Sealed Lead Acid batteries only 750 cycles and NiMh batteries only 500 cycles)
3. Safety
The safest battery in the world till now, which does not burn with 30V charge voltage and it does not explore when you puncture the battery. UL approved.
4. Light weight and smaller dimension
The dimension is smallest and the weight is lightest when compare with other battery. 1/3 weight of SLA, 65% weight of NIMH.
5. Great capacity and more powerful, rechargeable battery
High discharge current, 1C continuous, 3C pulse for normal cells and 20 C for special design
We can install many single cells in series and in parallel and it can fully discharge
6. Good thermal stability: - 40°C to 70°C
7. Back fast charge, good consistence, no memory effect, can equip battery charger.
Can be recharged anytime, no reduction of the capacity
8. Widely application, customize solutions, mass production, OEM/ODM/buyer label provided.
